The Welsh surname Blevins is an anglicized form of the Welsh name  ap Bleddyn, a byname meaning ‘wolf cub’, from blaidd meaning “wolf.” Blaidd was used in medieval Welsh as a term for a hero. The name is first found in the area around Denbighshire in the 11th Century when Meredith Ap Blethyn was Prince of North Wales. William the Conqueror seized the Prince’s castle at Oswestry in Shropshire after the Norman invasion of 1066 but he retained his estates in Wales.  The name is first recorded in America in 1856 when John Blevins arrived in Allegheny county, Pennsylvania from Wales.
